When the coating film of the waterproof layer is 1.0 mm thick, the usage is about 1.7 ~ 1.9 kg/m2. (Actual usage depends on the substrate condition and coating thickness.)
The coating film thickness of the waterproof layer shall not be less than 1.5mm, and the thickness of the vertical plane shall not be less than 1.2mm.
The product mix ratio is liquid: powder = 1:1.2 (mass ratio).
Substrate treatment → additional waterproof layer in detail → coating for large-area waterproof layer → quality inspection and acceptance → application of protective and isolation layers
The normal application temperature is 5 ℃ ~ 35 ℃. Application is not allowed in rainy weather.
Substrate treatment: The substrate should be flat, solid, clean, and free of visible water, ash, and oil stains. Internal and external corners and tube roots should be subject to arc treatment.
Coating ratio: Refer to the product certificate for the mixture ratio. First, add the liquid material into a mixing bucket. Then, slowly add the powder material in the process of mechanical mixing, and mix evenly. The prepared coating should be used up within 2 hours. It is forbidden to add water again in the use process.
Additional waterproof layer in details: An additional layer should be made for internal and external corners, pipe roots, drainage outlets, and other detail nodes, which are to be coated 2-3 times, and matrix reinforcement material shall be sandwiched to make the waterproof coating fully permeate the matrix layer, without wrinkle and edge warping.
Coating for large-area waterproof layer: For large waterproof layers, it is proper to coat the facade first and then the planes, with 2-3 courses of coating applied. However, the next course can only start after the previous coating is dry, and the direction of the coating should be vertical to that of the preceding coating.
Application of protective and isolation layers: In a humid environment, the drying of the product will become slow, and the drying time should be appropriately extended. After the waterproof layer is completely dried, the closed water test should be carried out. After acceptance inspection, the protective and isolation layers should be applied according to the design requirements.
